Solution
40 rupees : 120 rupees
= `40/120`
= `(40 div 40)/(120 div 40)` (HCF of 40 and 120 = 40)
= `1/3`
= 1 : 3

A doctor reports blood pressure in millimeters of mercury (mm Hg) as a ratio of systolic blood pressure to diastolic blood pressure (such as 140 over 80). Systolic pressure is measured when the heart beats, and diastolic pressure is measured when it rests. Refer to the table of blood pressure ranges for adults.
| Blood Pressure Ranges | |||
| Normal | Prehypertension | Hypertension (Very High) |
|
| Systolic | Under 120 mm Hg | 120-139 mm Hg | 140 mm Hg and above |
| Diastolic | Under 80 mm Hg | 80-89 mm Hg | 90 mm Hg and above |
